Title: METHOD AND SYSTEM FOR ESTABLISHING PUSH-TO-TALK COMMUNICATION
Abstract:
Disclosed are a method and system for establishing push-to-talk communication. The method comprises: a calling terminal initiates push-to-talk encryption communication, selects an encryption key, and sends the encryption key to a push-to-talk dispatching server, so that the push-to-talk dispatching server sends the encryption key to a called terminal; the calling terminal establishes an encryption call with the called terminal, and enters the encryption communication. Since the key is selected by the terminal initiating the push-to-talk encryption communication, without using a key distribution server (KDS), thus avoiding heavy reliance on the KDS. The computation and communication burden of the KDS is reduced, and it is avoided that failure of the KDS causes an operational failure of the entire system.
